Image analysis of PV module electroluminescence
Reliability of Photovoltaic Cells, Modules, Components, and Systems X, 2017Electroluminescence imaging can be used as a non-invasive method to spatially assess performance degradation in photovoltaic (PV) modules. Cells, or regions of cells, that do not produce an infra-red luminescence signal under electrical excitation indicate potential damage in the module.

Comparison of electroluminescence image capture methods
2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC), 2016In the field of photovoltaics, electroluminescence (EL) imaging has proven useful in determining the degradation of solar panels, primarily through use of expensive equipment within a confined lab setting. This study explored the potential of conducting EL imaging using relatively inexpensive equipment. Factors that heavily influenced the quality of EL

Estimation of Shunt Resistance by Electroluminescence Imaging
2014In the present work, an approach has been presented for estimation of the quantitative shunt resistance values of linear shunts in crystalline silicon solar cells by electroluminescence imaging. In this method, electroluminescence intensity is related with the actual shunt value considering the voltage and current across the shunt.

Electroluminescent large - area image display
Displays, 1980Abstract This paper views the state of the art of a large area electroluminescent image display, which includes powder and film screens excited to luminescence by ac or dc voltage. Such screens appear to have potential only if they are completely integrated with a controlling tft circuitry.

Photoluminescence and Electroluminescence Confocal Imaging of an OLED
ECS Meeting AbstractsIn recent years organic light-emitting diodes (OLEDs) have become one of the leading technologies for full-colour display panels in high-end smartphones and televisions. This rapid growth in use has occurred because OLEDs offer an all-around superior performance to liquid crystal displays (LCDs). For example, they are thinner, lighter, more flexible,
